Need photoshop help, how to enhance color of rainbow?
 

Hey guys could anyone give me some help with this, it is way beyond my knowledge of photoshop. I want to enhance the colors in this rainbow so they are more prominent, is it possible to do without messing up the rest of the colors in the image?

I tried..but there's not much colour in the rainbow to boost..and im not that good at photoshop. so the differnence is not big..but well:

edit: i just selected the rainbow and boosted red, yellow, and blue.. and +10 contrast..[surrender]

Ok, i've got 3 versions...

1st one (left everything untouched except the rainbow, pushed the saturation a little too far on the rainbow.)

2nd one (just a change in crop and image size, tried to get rid of the chair and ceiling part)

3rd one (basically tried to adjust it like i'd want it. desaturated the rainbow a little bit to take the distortion back out, cropped off the blurry interior part, upped brightness/saturation about +4, and then rotated/resized/sharpened)

To adjust the saturation on just the rainbow, i used the sponge tool (same little block as dodge/burn tool) and set the option to saturate at 50% and just kept going back and forth over it until it looked strong enough (no idea what brush size I used). You can also do use the same tool to desaturate.

Heres a small version of what id did in about 2 minutes (and im proud of it cuz i just killed a 40 in under 30 minutes)

if ya like it letme know and ill send you the full size via email

It's a picture I took out of a train from Alaska.

Really wow, i swear that girl looks like the one off the longest journey
looking out the window.Maybe i'm having flash backs!

Holy ****!!! What did you do there to improve the colours so much?? - Sorry I'm a complete noob but that change seems amazing!

He cranked up the color saturation (which is generally a bad thing, because it makes the image look horribly un-natural).http://www.discussworldissues.com/fo...lies/wink1.gif http://www.discussworldissues.com/fo...s/biggrin1.gif

But how do you do it in photoshop? Coz i am sure a little bit increase may help improve the photo

Image > Adjustments > Hue & Saturation

Adjust to taste.http://www.discussworldissues.com/fo...ies/smile1.gif

Thinking out loud: If you want to be a bit arty:

Why up the saturation of the rainbow?

Why not Desaturate eveything elseto greyscale?

Rainbow doesn't look fake and makes it look more colour ful than it previously seemed.

I'll have a go when I get some time and post it if I think it looks good.

this is about as far as i can take it without the whole image looking oversaturated:
